1 Road/Channel Relay Module (with light coupling) 12V

1 Road/Channel Relay Module (with light coupling) 12V

This module is a 1 Road/Channel Relay Module (with light coupling) 12V that meets the safety standard because it has an isolation groove between the control and load areas. It uses optical coupling isolation technology.

The triggering of this module is reliable and stable. It has a double FR – 4 circuit board design and a high-end SMT process. It also has indicators for power and relay operation. The relay terminals (C, NC, NO) are easy to wire up through screw terminals. The relay is safely driven by transistor BC547, which protects your input device, such as Arduino, from the relay circuit.

The inputs of this module are isolated to protect any delicate control circuitry.

It can be controlled by a wide range of microcontrollers, such as Arduino, AVR, PIC, ARM and so on.

The use of such high-voltage relay eliminates the risk of heating up of the relay as electromechanical relay limit the current consumption in accordance with a voltage rating.

Module interface:

The positive (according to the relay voltage VCC: connect power supply)
GND: connect power negative.
IN: relay module (effective) high-level trigger signal trigger end

Meaning of High level and Low-level

1. High-level trigger refers to using the anode voltage at the VCC connection way of a trigger and triggers the end when the trigger side has a positive voltage or to trigger voltage when the relay is off.
2. Low-level trigger refers to using the negative voltage at the GND connection way of a trigger and triggers the end when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.

Features 

1. Equipped with high-current relay 10A@250VAC / 10A@30VDC.
2. It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc
3. High-quality screw terminals (Terminal Block) provided (C, NC, NO) for quick and easy connection.
4. A freewheeling diode to protect your microcontroller.
5. Input Signal Pin connected to Burg stick for easy accessibility.
6. LED status indicators to indicate the relay ON/OFF status.
7. Mounting holes provided
8. Signal input with a high-level signal, the common and often start conduction.
9. The relay can directly control all kinds of equipment and load.
10. One often opened a normally closed contact.
11. Blue KF301 terminal line more convenient.
